[PATCH] net-dbus: Raise exception at 'introspector' if network is lost

[Pavel Strashkin]

D-Bus is the protocol with a strict specification. Inside
dbus/dbus-protocol.h i've found the following errors which binding
probably should check for and do nothing:

395 /** Interface you invoked a method on isn't known by the object. */
396 #define DBUS_ERROR_UNKNOWN_INTERFACE
"org.freedesktop.DBus.Error.UnknownInterface"

391 /** Method name you invoked isn't known by the object you invoked it on. */
392 #define DBUS_ERROR_UNKNOWN_METHOD
"org.freedesktop.DBus.Error.UnknownMethod"

What do you think?
